Abstract: 376,848. Motor vehicle steering gear. LJUNGSTRÍM, B., 83, Linnegatan, Stockholm. April, 21, 1931, No. 11788. Convention date, March 5. [Class 79 (v).] The steering gear, which may, e.g. be of the worm-and-wheel or screw-and-nut type, is movably connected to the body or frame of the vehicle so that the linkwork by which it is connected to the steering wheels is not affected by the movements of the wheels due to their elastic connection to the frame. The invention may be applied either to independently sprung wheels as shown, or to wheels mounted on a common axle. In the construction shown the steering wheels 1 are mounted on steering pivots 4 on arms 3 pivoted in frame bearings 5. Each wheel is steered by a separate steering gear 6 operated by a steering column 21 and having a spindle 7 carrying an arm 8. The arm 8 is connected at its free end by a link 10 to the steering swivel 11 of the corresponding steering wheel, and is further connected at its spindle end by a link 9 to the steering swivel, the links 9, 10 being parallel. The steering gear 6 is carried by a frame member 2, which may form a casing for the wheel 1, the connections between the gear and the member 2 being such that the gear can move transversely of the vehicle to a limited extent, this transverse freedom being necessary on account of the linkage between the steering gear and the corresponding wheel 1. The gear 6 may be connected to the member 2 by short parallel links constituting a parallel motion, or the connection ,as shown in Figs. 3 and 7, may comprise a lug 18 on the gear, a bracket 20 on the member 2, and a pivot pin 19 connecting the lug and the bracket. The steering-gear spindle 7 projects through a hole in the member 2, this hole being sealed by soft packing rings 29, 30 held in place by metal rings 27 and pressed against the member 2 by a spring washer. The steering gear, Figs. 8 and 10, may comprise right- and left-hand screw threads 33, 32 respectively engaged by slidable nut segments 35, 34 prevented from rotation by means of a rib 36 in the steering column 21 engaging slots in the segments. Each segment ends in a block 35a, 34a connected to a corresponding crank pin 35b, 34b on the spindle 7 by means of a member 35c, 34c, sliding in the block 35a, 34a and rotating on the crank pin 35b or 34b. Thus, when the steering shaft 31 is rotated, the nut segments and their blocks slide in opposite directions and rotate the spindle 7. Specification 376,847 is referred to.

Title: Improvements relating to Railway Traffic Controlling Apparatus.
IPC: B61L3/12
Filed: 1918-07-24
Abstract: 118,611. McKenzie, Holland, & Westinghouse Power Signal Co., (Assignees of Lewis, L. V.). Aug. 31, 1917, [Convention date]. Fluid-pressure; periodic.-The brake-pipe venting valve 27 is opened by a centrifugal governor at different speeds dependent upon the supply of pressure fluid to devices which offer variable resistance to the centrifugal forces tending to open the valve. Magnets H<1>, M<1> actuate valves supplying fluid pressure to or exhausting the timing reservoirs T, T<1> which are connected to the opposite sides of a piston 32 in the cylinder 37. The end of the cylinder 37 connected to reservoir T, is closed by a diaphragm 30 against which abuts a spindle 24 of the venting valve 27 on the brake pipe 110, which is urged to open the valve by a centrifugal governor device driven from the train axles. Thus when magnet H<1> is energized and the diaphragm 30 is under pressure the valve 27 is opened only at high speed of the train. The reservoir T<1> is connected to the other end of the cylinder 37 and pressure acts upon a piston 32 which compresses a spring 31 abutting against the spindle 24 so as to exert less resistance to the action of the governor so that the valve 27 will be opened at an intermediate speed. If both ends of the cylinder are open to atmosphere the spring 31 is not compressed and hence the valve 27 is opened at a still lower speed. The application of the brakes after the train has proceeded a predetermined distance past the track apparatus is dependent upon the apparatus controlled by the magnet W. This comprises a contact 104 which is normally closed but which may be opened by a pin 54a on a disk 54 which is rotatable, so as to move the pin 54<a> away from the contact 104, by fluid pressure supplied through the valve 63 controlled by the magnet W, against the spring 61. The piston 60 is moved backwards so as to tend to open contact 104 by the spring under control of a run-down device comprising a worm 58 and wheel 56 and a one way clutch 57, the worm 58 being driven by a ratchet 105 and a pawl 106 connected by a link 107 to a crank 108 on a train axle or a spindle 109 driven thereby. This mechanism is such that the worm 58 is always driven in one direction irrespective of the rotation of the spindle 109, and an irreversible. drive is provided so that the gear-wheel 56 can only be rotated by the spring so far as corresponds to the motion imparted to the worm by the movement of the vehicle.

Abstract: 725,867. Boring earth and rock; borehole conditioning process. HALL, J. E. May 1, 1953, No. 12147/53. Class 85. A method of conditioning a borehole 11 during drilling, to minimize loss of circulating fluid, comprises removing a drill pipe 12 from the borehole, attaching to or incorporating in the lower section of the drill pipe a stinger, i.e. a pipe having abrading elements on the exterior surface of the pipe, inserting the drill pipe and stinger into the borehole, and then reciprocating them longitudinally of the borehole. The surface of the borehole contacted by the spring fingers of the abrading elements is worked so that any excessive thickness of the mud layer on the wall of the borehole is reduced and the abraded mud redeposited in the caves, indentations and porous sections of the borehole. If the stinger is not of sufficient length to cover the entire zone to be conditioned, the conditioning is carried out at successive levels. The abrading elements comprise collars, which may move longitudinally of the pipe between stops thereon and rotate with respect thereto, and wire spring fingers extending to a circle of greater diameter than that of the bore. When the stringer is secured to the lower end of the drill pipe a drill bit or reamer may be attached to the lower end of the stinger.
